I was wondering if there is a way to create a LaunchDaemon for the wFTP server for Mac OS X Mountain Lion?

I've tried a couple of things mentioned by support and I've tried using the Mac OS utility called LINGON with no success. Part of the problem seems to be that the startup script requires you to change the working directory to the containing folder for the startup script, and the script has to be executed by the root or admin.

Any ideas about how to go about doing that? I don't like having to manually startup the server everytime I reboot the Mac, which actually isn't that often as I have a web server running on it also using MAMP.
